In these views 1 indicates thebarrel, 2 the stock having its end chamberedand 3 the casing in said chamber. This casing is formed with an enlarged part4 and a small part 5. This part 5 acts as the breech block and contains the firing mechanism. The.

part 4 receives the end of the barrel and acts as the breech casing or firin chamber. The.

- maganine is filled with cartridges.

Ad acent the front end ofthe breech cas-. ing is formed an inner annular groove 9 andslotsH-10 lead forward from this groove through the end of the casing. A slot 11 from dust and dirt.

till another object of the invention is to provide a single spring for actuating the firing pin, rnovlng the cartridges in the magazine and working the e ecting mechanism.

A further object ofthe invention is to make the barrel. easily and qnickly detachclub. W

able from the stock for the purpose of cleanthe the same orfor using said barrel as a ith the above and other objects in view the invention resides in the construction,

corohination and arrangement of parts set forth in-the following specification and fallring-within the scope of the appended claims.

passes rearwardly from said groove 9 to the H front end of the opening 6. The said slot has onewall thereof inclined, as at 12. The end of the barrel which engages in the easinn is provided with a lug 13 adjacent its end and said lug has its end inclined as at .13. An appreciable distance from the end of the barrel are located threelugs 14 spaced around the barrel and adapted to engage the slots 10 in the casing. One of these lugs is provided with an inclined end 14', 15 is a. semi-circular spring suitably secured to the outer part of. the casing; and carrying 9. lug 15' .for engaging the lug 13 to hold the barrel in the casing. By reason of the inclines on the lugs it will beseen that the lug on the spring will be pressed to one side to permit the gun barrel to be pressed into firing position without touching the spring and also will permit the barrel to he slid into ejecting position but the spring will prevent thelug 13 from passing its lug 15 and thus preventthe barrel from belng e'ntirelywithdrawr. from the casing. 'When thebarrel is to be entirely withdrawn the springis bent outwardly to permit the lug 13 to pass by thelng' carried by the spring.- It will be seen that theslot 11 is to one side of the adjacent slot 10 so that after the lug 13 is passed into said slot and pushes up the lug carried by the spring, it is necessary to give the barrel a part turn in order to place the lugs 13 in slot 11. The incline on passinto the annular groove and thus per mit the barrel to be given a partial turn 15 the lugs 14 out of alinement with the slots 10 and the lug 13 will engage the side of the extension 7 at the rear end thereof. The lug 14 which has the incline 14' is so formed that when the barrel is given a partial turn to the right it will force out the spring and permit the barrel to be pulled out into ejecting position. The lug 13 will prevent the barrel from being entirely withdrawnunless the spring is actuated.

The magazine is indicated by the numeral 16 and this magazine has an eXtension 16 on which is formed the trigger guard 17, p The trigger 18 is pivoted to this extension. The magazine and its extension fit into an opening in the underpart of the stock and-are held in position by screws 19 at each end thereof which engage parts of the casing.

The firing pin 20 is located in the breech blo k and is under the control of a spiral sp ing 21 which surrounds said pin. The f rward end of the pin, adjacent its pointed nd carries an enlargement 22 which is provided with a socket 23 and a flattened part 24 on its upper side forming a projection '25. 26 indicatesa sear having an upwardly extending arm27 ending in a. rounded 28 which engages the socket 23 so that the 4 pin. A collar 29 is carried by the firing pin and is provided with a forwardly extending lug 30 on its lower side which is held in engagement with the arm 27 of the sear by the spring 21. This spring and'collar tend wardly as shown in Fig. 2. provided with a front extension 31 having an inclined end 32 and a centralprojection 33. The front end of the sear is also provided with an ejecting lug 34. As will be seen, the forward end of the sear with the ejector lug and the extension 31 works in an opening in the bottom of the casing to one side of the magazine opening, the ejector lug working in a slot in the front end of the breech block. As will be seen from Figs. 4 and 5 the extension 31 extends in an inclined direction over the magazine opening so as'to engage the topmost cartridge and hold it in the opening.

extension 7 the lugs 14 enter the slots 10- into firing position. This turn will throw part:

sear is pivotally connected with'the firing to hold the sear with its front end tilted up- Thescar is .35 is the extractor placed in a depression having a. lug 36 thereon engaging-a slot 37 in the upper part of the breech block and adapted to be struck by the projection 25 on .the enlargement'22 of the firing pin in the extractor for holding the device in its rear- Ward orforward positions. This device 1s.

provided with a collar 45 which surrounds the rear end of the breech block and the front end of the device passes through an opening 46 in the rear end. of the casing. 47

indicates a thumb-engaging part on said devlce for sliding the same. The end of the breech block is closed by a cup-shaped mem- .ber 48 which has screw-threaded connection with the end of the block and has an opening in its end through which the end of the firing pin passes. This member also holds the safety device in place by fornlihg an abutment for the collar of said device. The

cup-shaped member carries, a. post 49 which passes downwardly through the stock and is provided witha screw-threaded hole for receiving one of the screws 19;- This post in the upper part of the breech block and also carries the pivot pin 50 on which the sear actuating lever 51 is pivoted. The cartridge elevator device 52 is also pivoted on this pin. The lever is of triangular shape and has one corner thereof resting on the trigger 18 and its other corner engaging the rear end of the sear when the trigger is operated. The elevator device comprises a finger 53 extending into the magazine and a second finger 5'4 pivoted to the first finger v by means of the ears 55. This second finger is of less length than the first finger so as to engagethe butts of the cartridges. The rear end of the second finger is i ounded as at. 56

and engages the botto1n-0f"thc breech block.

The rear end of the first finger is extended upwardly beyond the pivot pin and is pro vided with an eye through which the firing pin passes and the end of the coiled spring It will thus be 21 engages this extension. seen that the front ends of the fingers tend to rise under the action 'of said spring so as to force the cartridges from the magazine into the breech casing. When the barrel is in ejecting position the part 23 on the oxtension 31 of the sear will hold the cartridges within the magazine as before described and a cartridge will not be released until the barrel is slid forward and engages the 59 is opposite the same.

till

may be determined.

moving upwardly by the barrel itself. As

the barrel is moved rearward toward the breech block. a semi-circular groove 58 in its end will the end of the scar and push said sear rearwartlly and said sear is connected with the firing pin it will move said pin backvvardly against its spring. When the barrel reaches the endof its move ment and is given a turn to place it in firing position a notch 59 communicating with the end of the groove 58 in the barrel will come opposite the end oi. the sear so that when the trigger is pressed and the sear operating lever forced upwardly said scar operating lever will engage the rear end of the sear so that its forward end will pass through the'notch 59 and thus permit. the spring to force the firing pin forwardly and so explode the cartridge. It Will be seen that the trigger cannot be pulled until the barrel is in exact firing position as the groove 58 will prevent the sear being moveduntil the slot As before explained the lugs on the barrel will prevent said barrel from being turned until said barrel is moved the full length of the casing. Thus there is no danger of thegun being fired prematurely. l l hen the safety device is pushed forwardly it will engage the lug: 13 and prevent the barrel osing turned and its collar 45 will come under the end of the sear and prevent the same from being" 10W- ered to release the firing pin. i l/"hen the barrel is movecl'forwardly to open the easing it will release the extension 8]. of the sear and this member will be thrown out wardly by the spring 21 engaging the collar 29 so that the ejector Will throw out the cartridge. The extractor will remove the cartridge from the barrel as said barrel is moved forwardly. As before stated the extractor is raised as the sear is pushed rear- Wardly by the barrel and this movement is completed by the head of the cartridge en gaging the incline 39 so that the extractor will engage the groove in the headfof the cartridge.

60 is a gage rod pivoted to the elevator device and passing through a hole in. the rear of the trigger guard. This rod is pro vided with a series of notches in its end so that by counting the notches the number of cartridges remaining in the magazine lit wi shells c new a longitudinal movement of the barrel combined with aslight turning movement thereof. Thus the gun may be shot number of times without removing it frointhe shoulder. Attention is called to the fret that all the parts are controlled by a single spring.

I provide an improved sight for the rear part of the barrel. This si ht e 4 1pri;.es an enlargement formed on the hairs] and so located that it will contact with :the breech casing when the barrel is in firing position. This enlargement is provided-With a conc'ave depression in its upper face, and this face has a groove 91 therein, the side Walls of which are undercut. A curved st1lp'92 with beveled edges has sliding movement in said groove and forms the niova tle member of the sight. The rear end of tlis strip provided with the usual notch 93. The stri is prevented from being moved out of: the groove by the spring-controlled pin 9i engaging the groove 95 in the bottom of the strip. The strip is held in adjusted position by means or" the set screw 96. The parts may be provided with a suitable scale for indicating the distance the sight is to be set for.

When the gun is to be used as a single shot the simplicity and advantages of the invention will, it is thought, be perfectly apparent to those skilled in the art to which such invention appertains without further detailed description.
